"Abandoning fishing the deep, you took up the rod of the Cross..."

St. John the Theologian (source)

  
Abandoning fishing the deep, you took up the [fishing] rod of the Cross wisely in all things, and caught up the nations like fish, O all-praised one, and as the Lord spoke of you, He made you to be a fisher of men, drawing up towards piety. Therefore, you sowed the knowledge of the Word of God in Patmos and Ephesus, who bore fruit through your words, O Theologian Apostle. Intercede with Christ God that remission of offenses be granted for those who celebrate your holy memory with fervor.
-Kathisma for the feast of St. John the Theologian

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
